Do not short them. Probable pinout of MxLT tuner on PCB Antenna input and loop output were very easy to identify since the original antenna connectors were soldered into those places. The tuner is a an I2C slave device. In the end, my tuner had fewer pins than the original one in the case. Frequency conversions are performed by mixing two signals the incoming RF with a local oscillator. If you do this, remember always to tune set tuner frequency Practical build of TA receiver on 36 MHz will be in the updated version of this post.

This should be built inside a can you know those RF can coils inside every radio.

You will hear neighboring stations while adjusting local oscillator coil, because signals from a piece of I went for the first method and built a double conversion receiver. Probable pinout of MxLT tuner on PCB Antenna lihux and loop output were very easy to identify since the original antenna connectors were soldered into those places. The mixing result must be an IF at a common frequency, such as the Take the IF from tuner, consider it as any RF signal and perform an extra conversion.
This IC can set IF center at 9.

But, a closer look at the tuner which was basically an area of the PCB enclosed in metallic box revealed only a few tracks coming out of the tuner area. I will show you how I took it out from a receiver so I can use it in my projects. First of all I had to trace some lines due to the lack of pinout information. The tuner is a an I2C slave device. Probably this is the IF output.
Fi1 will chop all ,inux except those around If you do this, remember always to tune set tuner frequency Another two tracks come out from MxLT and are capacitor coupled.
It has a programmable IF output and it can receive anything from 44 to MHz. Knowing this there are three approaches: IF inversion does not affect the signal unless your detector is not centered on the right IF frequency.
The frequency step of the tuner is This is actually called double superheterodyne receiver.
After this frequency conversion, the resulting intermediate frequency signal is passed to a demodulator. Subscribe Don’t forget to check your email and confirm subscription. I assumed those are I2C bus lines.
Frequency conversions are performed by mixing two signals the incoming RF with a local oscillator. The practical disadvantage of this double conversion is that you have to build and adjust the local oscillator LC pair.
The power supply line was assumed to be the track that has a greater width than the others and has some capacitors connected to ground. Receiver specifications said it can receive to linx to MHz.

Second approach requires impossible to find components while the third is an option only when tuner can output an IF closer to standard FM IF. You know you got the right L. Therefore local oscillator L. I re-used a metal box from a broken TV tuner. Adjustment is done by setting the tuner to a frequency of a radio station and then tuning the coil until you receive it. Then I cut really the PCB and placed the tuner inside a metal box with easy mmxl5007t make connections.
Tuner PCB in a new metal case Everything was connected with tiny pieces of thin wire to a small piece of circuit board that held also the pins on the metal case. Also Fi2 must be replaced. I came up with an Arduino library for MxLT.
